The menu items in Dreamweaver are listed in the menus.xml file. When you add an extension, an entry for the extension is made in the menus.xml file.
Menu organization is changing in this release because a new menus.xml file will overwrite the previous menus.xml file. Because the previous menus.xml file – which contained Dreamweaver extensions – will be overwritten, menu entries corresponding to these extensions will no longer be displayed after the update.
To display previously installed extensions, do the following:
1. Click Help > Manage Extensions.
2. In the Adobe Extension Manager, use Ctrl-click or Shift-click to select extensions that you want to enable.
3. Right-click and select Disable.
4. Right-click again, and select Enable.
